In such a case as that what you "see" does not exist.
What see/saw was "tampered with".
It isn't your eyes that deceive at all. It is whatever nefarious behind the scenes liars do that is the deceiver.
Dare you ever BET YOUR LIFE on what you hear or see? BET YOUR LIFE on the TRUTH? You can't. "Truth" is fleeting and often deceiving and isn't at all what you are manipulated to believe. NOT AT ALL.
